When Obama says the "rich" have to sacrifice too...does he only mean rich Republicans?

I'm not putting source links cause i'm tired of doing that but you can google this. The top 1 % richest people pay 40% of all taxes. With the top 50% of earners paying 97% of all taxes. The Bottom 50% only pay 3% of taxes. Obviously none of the politicians want us to know this. The rich are paying almost all the taxes. Obama really can't have them pay much more. So since Obama knows this then why does he say he can have the rich pay so much more of the taxes? Hmmm.
