Election Predictions

Happy Election Day!

Update: To check live results for the Senate Race as each state closes, go here; Huff X Pollster; Election 2014

For weeks now, I have been following Sam Wang’s election notes on the Princeton Election Consortium blog leading up to today’s election. I hope he is wrong; but, it “appears” the best the Democratic Party can do in the Senate is 51 seats and the Democrats could end up with as few as 45 seats in the Senate. The later would be tantamount to a complete role reversal. Then the issue would be, could a rather complacent President Obama play the spoiler and veto Republican objectives for the next two years as there would be no 2/3rd in the Senate to over ride him.

Senate Race Predictions:

Sam Wang: “The calculations will test the question of how well we can do with polls alone. As always, we did not do any house-effects corrections or fundamentals-based modeling. This is a polls-only snapshot.

The error bars are SEM of the polled demographic. To calculate win probability, I have incorporated an additional possible 2.5% error to account for polling error/bias. “

Gubernatorial Race Predictions:

To calculate win probability, I have incorporated an additional possible 2.5% error to account for polling error/bias.”

I hope the margin of error is correct (or greater) swaying in favor of the Democrats today. Two more years of Republican control of Congress is just unimaginable. David Rothchild at Huffington Post had this to say about margin of error; and how it impacts Democratic candidates; “95 percent of the time the election outcome should lie within that interval. We find, however, that the true error is actually much larger, and moreover, polls historically understate support for Democratic candidates.

I will be happy when the day ends to be free of the election advertisements as put out by the political pacs replete with the outright lies. Who would have ever thought one man, one African American in the Presidency would have caused such a maelstrom of emotion discontent. If many of the malcontents are not used to it by now; just wait, the mix of the population is changing and heavily in favor of minorities.
