All but two members of the U.S. Senate are either Democrats or Republicans. As a result of this fact, it shouldn't be too challenging for a media organization to, you know, double check the party affiliation of a senator before tweeting that they may be suspending their campaign.
This task is apparently too challenging for the folks over at Talking Points Memo, a left-leaning site, who tweeted the following last night:
Sen. Walsh (R-MT) cancels public events, fueling speculation he may drop out of Senate race after plagiarism scandal: http://t.co/bahJeyyXe4— Talking Points Memo (@TPM) August 6, 2014
One small issue: Walsh, who is accused of plagiarizing about a fourth of his master's thesis, is not a Republican. He's a Democrat—something a two-second search on Google would have revealed.
Talking Points Memo has not corrected the tweet, although the linked article does properly identify Walsh's party affiliation.
