On November 2, 2010, Perry handily won re-election to an unprecedented third four-year term in the general election. He carried 226 out of 254 counties and polled 2,733,784 votes (54.97 percent) to White's 2,102,606 votes (42.28 percent). Perry made history by becoming the first Texas governor to be elected to three four-year terms and the fourth to serve three terms since Shivers, Price Daniel, and John Connally; his third term began on January 18, 2011. The Koch network gave Rick Perry $76 000 in 2010, in relation to the Texas Gubernatorial elections. Since the beginning of his presidential campaign, Perry has made what he calls the economic success of Texas the centerpiece of his campaign. According to Perry and his supporters, the state economy has improved as a result of his policy, including the lack of an income tax and predictable regulation. Others, meanwhile, have questioned whether the Texan economy is truly as successful as Perry claims. As of August 2011, Texas has an 8.2% unemployment rate. In comparison, the national unemployment rate was 9.1% in August 2011. 25 states have a lower unemployment rate than Texas, and 25 states (including the District of Columbia) have a higher unemployment rate, meaning that Texas has median unemployment among U.S. states. Between June 2009 and August 2011, 237,000 jobs were created in Texas. But when comparing population growth to the unemployment rate the influx of new job seekers has caused the UI rate to appear to be changing only slowly, when in fact the job creation rate has kept pace, or exceeded the influx of new population. According to a March 28, 2011 report by the Bureau of Labor Statistics, 9.54% of hourly-paid workers in Texas are paid at or below minimum wage. In comparison, the national percentage is 6.0%. Among the 50 U.S. states and the District of Columbia, Texas has the highest percentage of workers paid at or below minimum wage; the state with the second-highest percentage is Mississippi, with 9.50%. As of 2011, 26% of the Texan population does not have health insurance. In comparison, the statistic among the entire U.S. is 17%. Paul Krugman, a recipient of the Nobel Prize in Economics, attributed Texas' job growth to its growing population, which he said decreased wages and attracted businesses to the state. According to Krugman, the high population growth in the state was due to a high birth rate, immigration from Mexico, and internal migration of other Americans, due to the warm weather and low cost of living – especially the low housing prices from less restrictive zoning policies, which he described as the "one area where Texas does in fact do something right."
