How do Democrats and Republicans change their stances before elections?

One aspect of that question would be looking at the primary process versus the general election. The primary is when different candidates- different Republican candidates, different Democratic candidates, we'll stick with those two parties for now- they run against each other to see who is going to be the nominee, kind of the flag carrier for the general election. So, who amongst the Republicans are going to be the guy who goes against the Democrats, and who amongst the Democrats are going to be the guy that goes against the Republicans. In that sense, the primary voters tend to be more ideologically or politically committed, so they tend to be more ideologically positioned, or in the Republican Party tend to be more Right, Democratic Party tend to be more Left. So you have to kind of move to the Right and move to the Left in the primary process. But then when you get to the general election, obviously you want to kind of move to the middle because now you're trying to capture as many of those people who are kind of center Right or in the middle as possible.
