Why do liberals say conservatives are not open to new ideas?

[Master Chief]

We were all sooo rich following Regans "Supply side,union busting,tax breaking" economy that the Savings and loan industry collapsed following his terms.
The President then couldn't blame him because he had been the Veep.
So he started a war instead.

Clinton cleaned up the mess, raised taxes on the rich and left office with a surplus !

Which the next Conservative spent on what ? Tax cuts for the rich. Then he started a war.

I understand the GOP isn't exactly a place of intelligence,but even they can see a pattern can't they ?
Are they so reliant on the short attention span of the public they are willing to try to run on it again ?
Go ahead,it should be interesting.
