From the Pew Research Center:
Few Americans know the specifics of political power in Congress. Asked about the legislative branch in a recent News IQ survey, just 38% of the public can say the Republican Party currently has a majority in the House of Representatives. About one-in-ten (11%) say the GOP controls the Senate, 18% believe the Republicans control both houses, 6% say neither and 27% admit they do not know. Republicans are more likely than Democrats to be aware of the details of divided power in Washington. Still, only about half of Republicans (49%) know that the GOP controls only the House, compared with 39% of independents and just 33% of Democrats. As with many political knowledge questions, older adults and those with a college education are more likely to know that the GOP controls the House of Representatives. In a separate question about Congress, just 43% of adults were able to identify John Boehner as the speaker. Nearly two-in-ten (19%) still believed Nancy Pelosi controlled the speaker's gavel.
And yet this vast political ignorance doesn't seem to slow people down in forming opinions about "the other side."
Let us all take some time to actually learn something before we spew our uninformed or ill-informed opinions.
