"When a Republican running as a conservative loses, you always say it was the candidates fault the election was lost. When a Republican running as a liberal loses, you always blame the voters for the loss."
Your statement is UNTRUE.
The voters are always the one with the last say.
It's the voter's fault when they nominate a conservative who has no chance of winning in a general election and it's the voters fault, when they don't turn out to support their candidate.
Is it the voter's fault when they nominate a liberal who has no chance of winning in a general election?
Except you assume it's always conservative voters who are doing that, when the reality is usually the opposite. For example, in the 2004 election, some of the liberal city captains/volunteers in the county Bush/Cheney team quit in the week before the election, so they could focus on Steve Poisner's Assembly campaign. That meant certain key areas were abandoned without time to find a replacement, so that they "evil conservatives" had to fill in as best they could. The "evil conservatives" worked their butts off until the polls closed at 8 pm, while the liberals were spending the day planning a victory party. The conservatives did all that despite their misgivings about a lot of policies, just so they could be blamed for everything that goes wrong by the likes of you.
