Do you mean that Republican primary voters became so uninformed that they nominated poor almost non-Republican candidates?
What "Republican" primary voters? For the most part, these primaries have been in blue or blue leaning states, with open primaries. If it had been that only registered Republicans were voting, you might have a point.
Seems to me that voters are more informed than ever. The candidates can't get away with half the crapola they used to, with the internet, YouTube and so on being used to show their lies. And the MSM can't control the information, either.
So my question is: if it's not information (in fact, voters have more information than ever), what explains the fact that the more conservative candidates got practically zero support among conservatives? Or does conservatism not really exist among voters? If the base is voting in the Republican primaries, is the base proving to be conservative or not?
These are some fundamental questions, but they have nothing to do with George W. Bush, I think.
