I wouldn't bet on it. Keep in mind that this is the democrat party we're talking about.
Actually, I'm not too worried about election fraud, especially outside of Omaha itself.
In case you didn't know this, for decades Omaha was run by one of the most venal, the most corrupt Democrat party machines ever invented, which was overthrown in 1961.
Vestiges of it still remained, however, and the last two mayors (D) tried to rebuild the machine from those bits-and-pieces, with some success. That's why the Magic One got one of Nebraska's five electoral votes, much to our embarrassment and shame, in 2008, because the bosses managed to create some more votes in the deep blue precincts.
I've been concerned about Omaha slipping back into the bad old days of Democrat bossism, but at any rate, in Bellevue, the vote counts are clean, never a scandal of the least bit.
