One favorite NewsBusters trope is to cherry-pick a generally obscure pro-Republican, andi-Democratic factoid and dare the "liberal media" to report it -- while, of course, itself engaging in the double standard of refusing to note corresponding factoids that make Democrats look good/Republicans look bad.
But lookie here:
At least 14 Republican members of Congress have refused to endorse or publicly support Sen. John McCain for president, and more than a dozen others declined to answer whether they back the Arizona senator.
Do you think that Sheppard or any other MRC employee will make note of this? Highly unlikely (though a commenter on Sheppard's post does).
