Input: Consider Input: Almost four years after George W. Bush left office , neoconservatives still have n't grappled with his worst failures , as Jennifer Rubin reminds us in the clip above . 
Asked to name Bush 's biggest mistake , she offers two answers : -LRB- 1 -RRB- "His failure to forcefully and promptly reply about the scurrilous allegation that he lied about weapons of mass destruction in Iraq ;" and -LRB- 2 -RRB- his choice at the beginning of his second term to pursue private Social Security accounts before immigration reform . 
As I see it , the Bush Administration was constantly avowing that it did n't lie about pre-war intelligence , and immigration reform was unlikely to pass regardless of when it was attempted . 
But the larger problem with these answers is the notion that Bush 's political mistakes were more grave than the numerous substantive errors that he made while in the White House . 
My own list of Bush Administration mistakes is much longer , but even controlling for the dramatically different ideological perspective of neoconservatives , Rubin 's picks betray a profound failure to grapple with a presidency that needlessly weakened America in multiple ways .

Output: George W Bush


Input: Consider Input: Shaun White Wins Gold In Halfpipe At The Winter Olympics
Updated at 10:15 p.m.  ET
Shaun White  pulled off a gold-medal comeback in the halfpipe  and Japan's Ayumu Hirano won silver on the strength of a phenomenal second run.
CORRECTION: An early version of this story reported that  White  had won silver — that was reported after the second run had completed. On his third run   White  won gold.
 White  missed out on a medal back in 2014  when  he  was hurt at the Sochi Games.  He 's now the only snowboarder ever to win three gold medals at the Olympics. And  he  did it by winning the 100th gold medal for the U.S. Winter Olympic team.
After the Japanese snowboarder's rousing run  the pressure shifted to James and  White . James seemed to take a very deep breath before he set off on his second run. The first section was great — but he couldn't get a clean landing on one of his final tricks.  White  came out with energy and speed — but  he  fell midway through  and mustered only 55 points.
The situation reversed in the third and final run  when  White  earned a 97.75 and both of  his  top rivals fell during  their  attempts.
This is the second Olympic medal for Hirano; he won silver in Sochi. He is also the reigning X Games champion in the halfpipe  having won that title last month  in a competition that  White  skipped.
 White  led a group of four American snowboarders who qualified for the finals of the men's halfpipe at Phoenix Snow Park in Pyeongchang; joining  him  were Ben Ferguson  Chase Josey  and Jake Pates.
 Ferguson  cleaned up  his  second run after a fall in the first. And after a strong final run earned  him  a 90.75   he  finished 4th; Josey was 6th and Pates was 8th.

Input: Consider Input: Investors had all but ruled out a rate hike at the central bank’s policy meeting this week and attention has largely been focused on who will be in charge of monetary policy at the end of Fed Chair  Janet Yellen ’s first term in February 2018.
President Donald Trump is set to announce his nomination on Thursday afternoon with Fed Governor Jerome Powell  a soft-spoken centrist who has supported  Yellen ’s gradual approach to raising rates  seen as having a lock on the job.

Nevertheless   Yellen  and some other key policymakers have said the Fed still expects to continue to gradually raise rates given the strength of the overall economy. In its statement  the central bank reiterated it expects inflation to rise back to its target over the medium term and emphasized that the unemployment rate has declined further.
