Super wealthy towns that heavily swung against Donald Trump

[Interlocutor is just not there yet]

Woodside, CA:

Median annual household income: $246,042

I don't have 2012 data,  but I'm going to assume that it narrowly voted for Romney

2016:
Clinton: 57.2%
Trump: 21.8%

According to the San Mateo SoV, she did a bit better than that

2016:
Clinton: 68.4%
Trump: 24.8%

2012:
Obama: 54.1%
Romney: 43.5%

2008:
Obama: 63.6%
McCain: 35.2%

It turns out my data for Woodside was before all the votes were officially counted. Thanks for the info!
Donald Trump getting crushed in Woodside is not surprising, but I'm surprised that Woodside also voted overwhelmingly for Obama. Despite the fact that the town is very wealthy, it seems that it has always been overwhelmingly Democratic.

Since 2004, although Trump collapsed here compared to recent history

2004:  Kerry  55.9 - 43
2000:  Bush  50.5 - 45
1996:  Dole  49.3 - 40.4 - 5.7
1992:  Clinton  38.57 - 37.41 - 23.1

Compiled some SoCal numbers. Unfortunately, too lazy to put in demographics. Out of the 27 six-figure cities, Hillary won 18 compared to Obama's 8 in 2012. Income & population are based on the 2010 Census
