I'm not whining but if you think Schumer is only 21 points ahead, you may need your head checked.
I have no problem believing Schumer will win by "only" 20-something points. Something like 62-37 isn't out of the question.
Actually, it's probably the most likely outcome assuming the Republicans and Conservatives agree on a candidate. 2004 was a bit of an outlier because it was a Presidential election year (higher turnout) and the Republican candidate wasn't cross-endorsed by the Conservative Party. Plus, the national winds are against the Democrats this cycle. And if all major NY races are expected to be blowouts come election day, Democratic turnout could suffer a little bit making the three big NY races a little closer than expected, but still double-digit blowouts.
