Republicans Switching Party To Vote Democratic

What is really behind the recent phenomenon of Republicans switching party to vote in Democratic Primaries and Caucuses? Are they doing doing this because they are disenchanted with the Republican Party or are they being mischievous. It somehow does not feel right that the Elections Laws are so broad that a people can switch parties for the sole purpose of undermining a candidate (Hillary) or party (Democratic) because people want to create mayhem, then switch back the very next day to ensure they are again Republicans come November, thereby giving John McCain an unfair advantage in the General Election.

We really have to examine the motives of these "College Kids" who are running around the country fawning all over Obama who "convinces" their parents to vote for Obama, then say its okay for their parents to revert to Republicanism. Do they 1) Understand that this is illegal 2) realize that this might result in the wrong person getting the nomination 3) Care that it puts the Democrats at a disadvantage the longer the primary process drags on and 4) One has to wonder whether they would actually turn out and vote this time. So far, all the talk about the turnout of young voters has been just that, talk and no action. Let's see if the put their pens where their mouths are.
