It has been noted by pundits over the last several years that the Republican congressional victories in 2010 and 2014 were because of voter rejection of Obama's policies, and that Republicans ignored this to their peril. Yet, each time, Republican Congressional leaders have immediately turned to attempting to work with Obama. Pew has released a poll showing that that pundits were right.
According to the poll, Republican voters want GOP leaders to challenge Obama more often. Since the GOP has failed to do so, some 65% of the respondents to the poll said that Congress has failed to keep its promises to voters.
