"with this said, why is it obamas fault gas prices have risen?"
Because prices are based on futures. When people know prices are going to go up, they buy now. If prices were going to go down, they'd sell now to cut their losses. (The price change is more immediate in either case--It doesn't inherently raise prices that speculators effect the market.)
Obama bans drilling everywhere he can. As world demand increases and Obama does all he can to keep production as low as he can, obviously he contributes to high prices.
"he is to blame for inflation too right?"
Inflation is not a magical beast. Inflation is what happens when the fed prints massive amounts of money to buy government debt. Obama has contributed to inflation by spending at a rate nobody has ever spent before, which the fed picks up the printing to keep up with. Obama has contributed to inflation with his massive stimulus bills.
"lets blame the stock market on him aswell why not"
The stock market is an awesome thing. But no, he doesn't get credit for it. He didn't create it. You sound a little confused.
