NI is specifically an employment tax. So not the same as an income tax, although, to the ordinary working person, it feels the same.
Tory supporters are predominantly over retirement age so they like changes that make pensioners better off.
There is no particular reason why people receiving one state benefit should pay tax on it, but not others with the same income.
The government revenue from NI and from Income Tax are two large sources of government funds. You can cut one and increase the other depending who you want to favour.
It is reasonable to argue that there is no point in having two taxes, just have one, but the maze of allowances and cutoff points is a bit of a tangle.
And if income tax was increased to make up the shortfall from NI, some people would complain that their tax had gone up.
