Two Gallup surveys that make absolutely no sense

Survey #1:

Americans' economic confidence, on a weekly basis, is now at the highest level Gallup has recorded since late May. The Economic Confidence Index score for the week ending Oct. 14 is -17, up from -19 the week prior and -21 the week prior to that. The current data are the first to include a full week of interviewing after the generally positive Oct. 5 jobs report.

Survey #2:

Half of likely voters now prefer Mitt Romney for president and 46% back President Barack Obama in Gallup interviewing through Monday. While Romney's four-percentage-point advantage is not statistically significant, he has consistently edged ahead of Obama each of the past several days in Gallup's seven-day rolling averages conducted entirely after the Oct. 3 presidential debate.
