Is it federalism if the president can veto a bill

what is the difference between federalism which is what would give the pres more power to do what he/she wants and anti-federalism is what gives the states more power basically making them there own little countries in a bigger country, THE USA, so you have a bill that is proposed, it is sent to congress has to pass with 51% majority, then to the senate 51% majority, then sent to the pres if he vetos it then it starts over and now it needs to be 2/3 majority for both the congress and senate and if it passes them then it will pass the pres and be passed.
