Assuming osmotic pressure is the (main?) culprit, why isn't the chlorine ion loose in your body after eating salt considered equally responsible for hypertension?

I have searched Google and Wikipedia, and cannot find an answer.

I have looked here at Stack Exchange, too.

Why is it that you always hear about how bad 'sodium' is for your diet, but every sodium cation comes with a chloride....

Could someone point me to an article, at least?

    $\begingroup$ I made an important change to your title: chlorine -> chloride. The latter is the anion in salt, which is presumably what you're interested in. The former may cause high blood pressure via a horrific death. $\endgroup$

    $\begingroup$ Not every sodium comes with a chloride ion. For instance sodium bicarbonate (baking soda), sodium nitrate (in preserved meats), monosodium glutamate (Chinese food), and many more that are used in food (or sometimes medicines). $\endgroup$

Osmotic pressure is not the main mechanism of sodium-induced high blood pressure.

high dietary salt raises cerebrospinal fluid [Na(+)]. This leads, via the Na(+)-sensing circumventricular organs of the brain, to increased sympathetic nerve activity (SNA), a major trigger of vasoconstriction

How NaCl raises blood pressure: a new paradigm for the pathogenesis of salt-dependent hypertension.
