Polls consistently showed Tester trailing in his bid for re-election, but he was victorious on Election Day.
Brodnitz said Republicans appear to him to have put too much stock in voter enthusiasm and national polls, which suggested that Romney and GOP candidates down ticket would perform better. He also said that they might have read too much into the massive crowds Romney was attracting to his campaign rallies in October.
“If you’re going to tell the story of this election, name of the story would be the case of the wrong metrics. Republicans were using wrong metrics to try and determine what was going on this year,” he said. “If Democrats did a better job than Republicans this time, it’s because Democrats were being more objective about what was going on.”
