The boundaries of the constituencies are determined by four permanent and independent Boundary Commissions, one each for England, Wales, Scotland, and Northern Ireland. The number of constituencies assigned to the four parts of the United Kingdom is based roughly on population, but subject to certain statutory regulations. England, Wales, and Scotland must have a total of approximately 613 constituencies, and Northern Ireland between 16 and 18 constituencies, and Wales at least 35 constituencies. The Commissions conduct general reviews of electoral boundaries once every 8 to 12 years, as well as a number of interim reviews. In drawing boundaries, they are required to take into account local government boundaries, but may deviate from this requirement in order to prevent great disparities in the populations of the various constituencies. The proposals of the Boundary Commissions are subject to parliamentary approval, but may not be amended by Parliament. After the next general review of constituencies, the Boundary Commissions will be absorbed into the Electoral Commission, which was established in 2000. Currently the United Kingdom is divided into 646 constituencies, with 529 in England, 40 in Wales, 59 in Scotland, and 18 in Northern Ireland.

I would go for a change: a mixture of the current system and a component of proportional representation. This would mean an overall majority would be unlikely. That is a good thing in itself, so rotten laws are not forced through Parliament.

Because our government is set up along a "winner take all" system.  Only the top two contenders in any race will ever be taken seriously, that's why we only have two parties.\n\nThe other countries that have multiple parties are one with parlimentary goverments.  With the parlimentary system, in the election you vote for a PARTY instead of a candidate.  Then each party get a number of MP's (Members of Parliament) based on their percentage of the vote and then the new MP's choose the prime minister.  Since your vote won't be "wasted" voting for a 3rd, 4th, or 5th party, people feel fine doing so in a parliamentary government.

If you want to keep your job you don't usually attack the incumbent party and PM! I would have thought it's as a result of tory lobbying and the police's recognition that they'll be in power in the next couple of year.

Some politicians pick their party based on what party is most popular at that time in order to get elected.\n\nLater, after they have established their power base, some switch to what they really believe. Some switch later on in the event their party is no longer the popular party because they want to stay in power.

Its an age related thing. People grow more and more conservative and in line with republican beliefs as they grow older. Not to say that everyone does, but most of your democratic supporters will be younger and the old granparents will often be Republican.

yes, unfortunately, not all current and aspiring politicians can be accomodated into the  parliament. Remember that in past presidential elections, everybody including lunatics file their candidacy for president.

Parties realign politically to meet the changing electorate.  This year the Dems picked locally more conservative candidates in red states.  So their members in Congress will be slightly more conservative than in the previous sessions.  \n\nParty conventions are held every 4 years to officially nominate candidates.  Delegates are selected by primaries and caucuses.  A majority is required to win.  The convention also writes the party platform.

C because House seats are determined by the population of the state.

I have no idea what you mean. There are 400+ members of the House of Representatives and 100+ Senators. Each is from a specific district or area in one of the States. What are you referring to?

The House of Commons is the lower house of the Parliament of the United Kingdom. Parliament also includes the Sovereign and the upper house, the House of Lords; the House of Commons is the dominant branch. The House of Commons is a democratically elected body, consisting of 646 members, who are known as "Members of Parliament" or MPs. Members are elected by the first-past-the-post system of election, holding office until Parliament is dissolved (a maximum of five years). Each member is elected by, and represents, an electoral district known as a constituency. The House of Commons is the source of the vast majority of government ministers and every Prime Minister since 1902, with the very brief exception of Sir Alec Douglas-Home in 1963, has been drawn from it (Home did actually rule from the House of Commons, however, taking a seat in the House shortly after being chosen as Prime Minister).\n\nThe House of Commons evolved at some point during the 14th century and has been in continuous existence since. The House of Commons (the "lower house") was once far less powerful than the House of Lords (the "upper house"), but is now by far the dominant branch of Parliament. The House of Commons' legislative powers exceed those of the House of Lords; under the Parliament Act 1911, the Lords' power to reject most bills was reduced to a mere delaying power. Moreover, the Government of the United Kingdom is answerable to the House of Commons; the Prime Minister stays in office only as long as he or she retains the support of the lower house.\n\nThe full, formal style and title of the House of Commons is The Honourable the Commons of the United Kingdom of Great Britain and Northern Ireland in Parliament assembled. The term "Commons" derives from the Norman French word communes, referring to the geographic and collective communities of their representatives. It is often misunderstood that "Commons" comes from the word "commoners", referring to those sitting in the House, similar to the way in which the name "House of Lords" indicates that those sitting in the "Other Place" are elevated to the Peerage. This explanation, however, is ahistorical. Both Houses, the Commons and Lords, meet in the Palace of Westminster. Both Houses have in the past met elsewhere, and retain the right to do so, provided the Mace is present.

not nearly as many as they used to. I think last time I read they had like over 100,000, maybe more. They don't bring in the ranks anymore because the Socialist Party USA has taken a lot of their potential members...

No one can expect all 500+ Representatives and Senators to be experts on all topics.  Each of them are assigned to multiple committees; these become their specialties.  These committees then explain the intricacies of each topic to the members of other committees.  They then make their votes, often trading support to gain votes for bills they support.
