he is devastating:

To recap: white students in Texas perform better than white students in Wisconsin, black students in Texas perform better than black students in Wisconsin, Hispanic students in Texas perform better than Hispanic students in Wisconsin. In 18 separate ethnicity-controlled comparisons, the only one where Wisconsin students performed better than their peers in Texas was 4th grade science for Hispanic students (statistically insignificant), and this was reversed by 8th grade. Further, Texas students exceeded the national average for their ethnic cohort in all 18 comparisons; Wisconsinites were below the national average in 8, above average in 8.

Perhaps the most striking thing in these numbers is the within-state gap between white and minority students. Not only did white Texas students outperform white Wisconsin students, the gap between white students and minority students in Texas was much less than the gap between white and minority students in Wisconsin. In other words, students are better off in Texas schools than in Wisconsin schools – especially minority students.

The Statistics are here from the NAEP standardized tests and they make a fool of Krugman and the Economist articles.

Just a reminder, Teachers in Texas don’t have collective bargaining rights.

In the old days it was always known that Jesters had the wisdom in the court, apparently it is still true today.

Ezra looks at the trend lines on President Obama and thinks liberals are worrying needlessly:

But so far as the polls go, Obama is doing okay among the left. In fact, as the graph below shows (click on it for a larger version), his approval trends among Democrats, independents and the country mirror Ronald Reagan’s ratings among Republicans, independents and the country almost exactly.

Tell you what Ezra lets make a bet. I’m a little hard up but I’m confident enough to make this wager:

You say Obama’s poll lines mirror Reagan’s? Fine. I’ll pay you $500 for every state Regain lost (including DC) in 1984 that Obama wins in 2012. You pay me $500 for every state that Obama loses in 2012 that Reagan won in 1984.

Or if those odds are too long for your trend lines, How about I pay you $10 per electoral vote that Obama gets in 2012 over Reagan’s total in 1984 and you pay me $5 for every electoral vote under Reagan’s 1984 total Obama wins in 2012. I’m broke and unemployed but I don’t mind giving you odds.

How about it Ezra, wanna put your money where your graph is?

Update: If any of you other liberals want to put your money where your confidence is come pony up
