The guy that lost (first McCain, then Romney) was a leftist Republican attacking Republicans like me for refusing to vote for Republicans who advance government tyranny.
They lost because they were too inclined to see government as the solution. They could attack Obama and the Democrats until they were blue in the face after the primaries, and voters were indifferent.
Republican presidential primaries aren't about choosing the Republican who does the best job of attacking Democrats -- we've seen what happens when it is: the candidates lose the general.
The Republican primaries are about choosing the Republican who does the best job of advancing Republican principles and values of limited government. That necessarily means attacking Republicans such as Romney and Jeb who advance principles and values of government tyranny as usual.
That attacking Democrats is the focus of Republican presidential primaries is no doubt a big part of the reason the Republican party has failed so miserably in selecting a conservative candidate.
You could not possibly be more mistaken, more wrong. That is exactly 180 degrees out of phase with reality. The exact opposite can be proven by history.
You need not fear this man, "Barak Obama." John McCain
