Unless the Republicans get busy and push voter registration for Republican inclined nonvoters this loss of Republican voters will continue because men, unlike corporate trusts, die!.
Part of the problem is the belief by Romney and his chief supporters in the GOP-e that there's a political middle made up of independent, undecided, moderate whatevers ~ who vote, presumably.
As I've been preaching for years, there's no such middle. Does not exist. Never did exist. This is not the 1793 French General Assembly!
The key to winning the presidency is simple ~ find Republicans, get them registered, make sure they vote for the party candidates. Then, have the candidate exhort them to get out there and get people to vote for the party candidates, and get people to the polls, or whatever other voting method we are using.
If the candidate is off somewhere speaking inoffensive platitudes and pie in the sky to the non existent undecided middle, he will lose the attention of the Republican voters.
I'm still waiting for Romney to initiate his campaign BTW. Dude even came to my neighborhood, but it was a closed, by invitation only, meeting with American Legion dignitaries.
Highly disturbing visit BTW. All the traffic disruption with none of the excitement that's supposed to come with a political gathering.
I don't think that explains much, if anything. Of course some voters die, voters of all ideologies. But young people become old enough to vote and every voters age by four years between each presidentail election.
And many younger voters who'd voted liberal for a time get hit with the reality of real life and eventually become conservative, thus adding to the conservative voters.
The makeup of the voter population isn't static at the older or younger end. There's always some movement in and out of all political parties.
