He's better than the alternative.
So basically your choice is gun barrel to the left temple or gun barrel to the right temple. (The results are the same)
If there are 2 people running of which neither plans of "reducing" the size of government which would you vote for? Of the 2 people running neither will strengthen the second amendment so where does your vote go? If you feel abortion should be limited and neither party does anything to curb abortion to which candidate goes your support?
The point here is that true conservatives, meaning the ones that support the letter of the Constitution, conservatives that fight for a balance of power between the federal government and the States and those that believe government should never grow any bigger than it absolutely has to are aiding in the take over of the party they only "think" is their own.
Who was the last conservative President that advanced the conservative ideology? Regan. And that was almost a quarter century ago! Yet conservatives continue to support a party based upon 2 or 3 items to bait you into voting for an ideology that is NOT conservative but either through empty promises or similarities republicans support those who have no intention of advancing the conservative ideology .
I think most people hoped that Bush (41) would continue the policies of Regan and to some extent he did yet he was not conservative and by in large the party continued to skate on the policies Regan had implemented.
Along comes Newt Gingrich (94?) who proposes a conservative agenda for the first 100 days of Congress and incumbents are replaced everywhere by republicans suggesting a real possibility that THIS COUNTRY IS FUNDAMENTALLY CONSERVATIVE but by the time of the next Congressional election there is no such contract with America and the people go elsewhere and support waivers.
Bush (43) wins in 2000 and aside from getting his shoes wet by the tears of Al Gore offers very little in the way of a conservative ideology other than a tax break after we had been attacked and when the county could least afford it and rebuild the Armed Forces previously gutted by Clinton.
In 2008 John McCain chose Palin for 2 reasons. A) She's considered a minority (to counter Obama's minority status of being black.........OK "half" black) and B) to sucker in conservatives to inadvertently support McCain only because Palin was more conservative than he was!!
So I ask you; when a republican seeks to win an election and doesn't based upon the idea that his own base believes he/she's moved too far to the left isn't there a very real possibility that in a race in the next election a candidate will be fielded who has to move back to the right to win the election?
As a follow up I might also add; If Romney should win the Presidency in the fall, why should he go out of his way to advance a conservative agenda when Rhino's and moderates aligned closer to center were the overwhelming force that put him in office?
